Was at work the other day when a co-worker and Harley owner started talking about the local 100hp club. I had actually never heard of this, so I asked him what it was … as he explained it, it’s an elite group of HD owners that have modified their bikes to such an extent as to reach the lofty heights of 100hp. He mentioned that obtaining this level of modification would cost him over two thousand dollars, so he is not considering it, but did ask me if I thought that would be worth modifying my bike to reach a similar goal. I was really trying not to laugh when I told him that I really didn’t need to change much since it starts out around 150hp. The look on his face was great, especially since he knows I paid half what he purchased his bike for.

I hope this posting is in the correct location … I wasn’t sure if I should post this under General FJR discussion … the Technical section because of the modification aspect … the Sport bike heading because of the immense 100hp level of performance … or because of the attempt to seriously trick out your Harley for speed and performance under the Jokes and fun stuff.

 
Was he talking at the crank or at the rear wheel. Your reply was a slight exaggeration if talking at he crank. A much bigger exaggeration at the rear wheel.

FJR at the crank is officially 145hp, 124-128 at the rear wheel. Still much better than 100.

I think that the admins like Harley bashing in another location. If you weren't bashing, give it a little time... the bashing probably isn't far off. It will definitely turn into it.

Personally, I probably would've put this post under "Other Bike/Bike Related Discussions"... but the other spots that you mentioned could work, too.

Oh, I think you chose the correct location because you have the three letters F...J....R somewhere in the text. <_< :dribble:

No, not really. I should have gone in Other Bike/Bike Related Discussion..

As a secondary point....it would have gotten moved to NEPRT and one or more of the three adjectives is covered. Regardless, please read this thread. Thx.

I would think rear wheel, the twin cam makes almost 92 crank hp stock. And $2000 bucks is cheap, ask how much it would be to add 25hp to the FJR without nitrous. :blink:

EDIT: You might also want to look at torque figures when comparing with HDs.

Well all I know is that no matter how much HP they put out the new ones are governed. My buddy at work can't get his HD over 100 MPH.

When he went back and asked the salesman why, he said he would have to put an aftermarket ECU in it. He also said that he may be able to get another 15 to 20 MPH out of it. Wooooooopy!!!!

The new Big Twin 96 makes 79hp at the crank, the mighty Twin Cam 88 made all of 72hp. Hopping up a Harley-Davidson is one of the most collosal wastes of money there is on the planet. They are made so you can be seen and heard. Those wishing a speedy, stealthy will choose from other choices, including Harley-Davidson's own VRSC, a liquid-cooled 60 degree powerplant designed by the folks from Porsche.

 
Once you're committed to riding H-D, you're sort of stuck with their performance.... H-D knows this and they've got all the screamin' eagle mods available to help you get maximum performance within their system. I was watching a TV program this evening and they had a bolt on supercharger kit that you could add to your Road King and it supposedly would boost it to 140 hp. It looked like it would add a ton of weight, and I can't imagine that it would do that well without serious remapping and some exhaust work. Maybe the exhaust work was included it was big enough and bulky enough.

When we bought the chassis dyno I went to the factory to be trained on setting it up and using it. The guy who did the training was running a dyno shop for profit. He had a chassis dyno with eddy current brake set up to absorb something on the order of 1000 hp. In any event, he was telling me that most of his business was kids who bought Honda Civics and then paid a fortune to modify them so that naturally aspirated they could make around 250 hp and blown they could get up over 500 hp. I guess my point is that people seem to like the idea of having something and then modifying it or customizing it so that they feel they have "the best one." There are guys here on this forum who do the same thing, i.e., continuously modify their bike trying to get a few more hp.

Somebody above made the comment that with H-D you really need to compare torques. I've got news for anyone who is thinking H-D has some magical torque figures. Their torque sucks too.... just look at any magazine's published specs. FWIW, most folks here probably realize that torque and horsepower are linearly related, with horsepower being equal to the torque in foot pounds multiplied by the engine speed in rpm and divided by 5250. This is true for any engine since its just the definition of horsepower. If an engine is making crummy horsepower figures, its torque figures aren't going to be that great either, unless its a 200 rpm steam engine or two stroke diesel or something.

I think a big problem for H-D is their volumetric efficiency, and their ability to get uniform and complete combustion. If NASCAR pushrod engines were as poorly developed, they'd be lucky to make 500 hp. Seriously.... No BMEP for HD. Sad sad sad state of affairs with those Motor Company goobers representing the US in the engine technology business. And yeah, I know Porsche helps. They're laughing all the way to the bank.

 
I find the Harley bashing quite amusing. I don't understand why people have to crap on anyone else's motorcycle. We should be happy that other people partake in our sport. Who really cares how many horsepower or how much torque a motor puts out and how much it costs to get there. If someone wants to spend $2K , $3K or $10K on their motorcycles then it is their business. I think life would be real boring if everyone only rode FJRs. There would be no diversification and we all would be drones. If people feel like they have to bash other peoples motorcycles then they are small people.

I have an 06 Harley Road Glide in my garage along with an 08 Harley Low Rider and an 07 FJR. All three are totally different bikes and I like each of them for what they are. I have put a lot of money into the Road Glide (over 5K in the motor) and have 20,000 miles on it. I have personally taken the motor apart and built it myself. It was a great learning experience for me. I can honestly say I know how that bike runs and if something goes wrong I know I can fix it.

I will admit that Harley's technology is not the most current and there are some idiots out there that ride them, but that can be said for ALL brands and ALL types and styles.

If your buddy wants to exceed the 100 hp club more power too him. The real key is exceeding 100 HP and 100 ft lbs of TQ.

Just about any bike that makes 100 ft-lbs of torque will also make over 100 hp unless its got a red line of less than 5250 rpm, or its making its torque in some unusually limited range.

Modern bikes with four valve pent roof heads routinely have very consistent nearly flat torque curves in the mid range and on toward the point where the volumetric efficiency begins to be problematic.

Torque is related to the brake mean effective pressure (BMEP). If a naturally aspirated engine is well developed, it is possible to get BMEPs up around 200 psi. I did some calculations on the FJR once, and I think it was maybe 150ish. I'm thinking that an HD, with its 60-75 stock hp, and its relatively large displacement, its probably considerably less.

An F1 engine will be in the ballpark of 200, as will a NASCAR engine. These are very different engines, but both are highly developed for their genre. A MotoGP motorcycle engine is in the same ball park. A highly developed sport bike engine will approach 200. BMEP is generally a good descriptor to sort out the engines that are well developed from those that aren't.

Egads, so I did a little research. In my first effort I used numbers posted on a HD enthusiast sight. Looked at HD's page, nothing (although they do report torque figures of 91.0 ft. lbs. @ 3125 rpm). So after your post I did some more looking. I found 10 different sites with folks claiming to know the hp figure, and not one of them were the same!

The low I found is 68, the high turned out to be the first one I reported. No one seems to be clear on the crank versus rear wheel hp. Good grief.

you do have a point, but just think, or just imagine the plethora of aftermarket farkles we would be able to install...every vendor making FJR parts, ok no day dreaming while typing...

amen :)

 
My V-rod would do better than 100. I never pushed past 125 but it was still pulling hard.
I am usually coming out of 3rd gear at about 125. :rolleyes:
Check the original posts doods, we're talkin' about HP here, not MPH.

FWIW my '04 H-D Ultra Classic showed 92 HP at the wheel on the dyno AFTER bumping the original 88" up to 95", installing gear-drive cams, a Power Commander, H-D EFI remap, pipes, SE air-cleaner and dyno-tuning.

Ok, after dumping all that money for HP... Now how much are we going to spend to make them handle.... :dntknw: :haha: :lol2:
Well. One could just buy a Buell cousin. More HP and much better handling. No need to modify anything. Not as fast as my FJR in a drag race but really sweet when the road gets curvy. :clapping:
